ROBERT R. ROBINSON gwaezg HIS ATTORNEYS Patented Aug. 4, 1953 HAND STAMP Robert R. Robinson, Dayton, Ohio, assignor to The National Cash Register Company, Dayton, Ohio, a corporation of Maryland Application January 16, 1952, Serial No. 266,639

4 Claims.

This invention relates to a hand stamp with adjustable type, and more particularly perta ns to one in which the type are mounted on slidmg flexible strips within a folding case, the case being opened to adjust the type and closed to expose the adjusted type for a printing operation. The folded case acts as a handle for the user to grasp.

The hand stamp is particularly adapted for use with resilient type, especially porous rubber type impregnated with ink.

The novel hand stamp is an improvement over that disclosed in application for United States Letters Patent, Serial No. 208,223, filed by George T. Brown, Jr., on January 27, 1951, now Patent No. 2,597,919, with respect to the mounting of the type strips in that springs are provided to keep them taut, by the provision of a movable bridge supporting the selected type at printing position, movement of the bridge from normal position projecting the selected type for inking, and by the provision of limit stops to prevent excessive printing impressions.

In a co-pending application for United States Letters Patent, Serial No. 266,640, filed the same day as this pplication, there is claimed a combination of this novel hand stamp with a reinking device.

Therefore, it is an object of this invention to provide a novel hand stamp with the foregoing features.

With these and incidental objects in view, the invention includes certain novel features of construction and combinations of parts, a preferred form or embodiment of which is hereinafter described with reference to the drawings which accompany and form a part of this specification.

Of the drawings: I

Fig. 1 shows the hand stamp in front elevation poised over record material.

Fig. 2 shows the substance of Fig. 1 except that the hand stamp and its type are in contact with the record material, this view showing how the hinges act as limit stops to prevent excess pressure and compression of the type.

Fig. 3 shows the hand stamp in side elevation, with the near sides of the two casing halves broken away.

Fig. 4 is a side elevation of the hand stamp with the near sides of the hinged ends of the casings broken away, showing the selected type in its projected position.

Fig. 5 is a view of the opened hand stamp looking at the adjusting mechanism, parts being broken out to accommodate the view to the sheet.

Fig. 6 is a detail view of the indexing mechanism of one of the type strips.

Fig. 7 shows the hand stamp in the receiving socket of the inking device can with parts of the can broken away to show the disposition of the various elements.-

Fig. 8 is a detail view of how the type strips are mounted and kept taut by extendable springs.

Fig. 9 shows the substance of Fig. 7 except that the type have been protruded by inward movement of the button at the top of the closed case so as to strike the ink-flooded re-inker pad.

Referring to Figs. 1, 2, 3 and l, the hand stamp casing consists of two halves and 2|, mated to form a unit when together, said halves being hinged at 22 and 23 by hinging screws to form a folding case, said screws being passed through ears 24 and 26 of the casing half 29, and ears and 21 of the other casing half 2|, and screwed into a hinge block 28, which hinge block is itself pinned to the sides of casing 2| by pins 29 and 30, the pin 30 being shown in Fig.5.

Referring especially to Fig. 5, the inner hollow side of casing half 2| has therein a sliding plate 3| which has attached thereto by the finger 32 a button 33 so that the plate may be pushed to the left by inward movement of said button 33,

as shown in Fig. 5, and returned to normal by' spring 34 as the button is released. Spring 34 extends between end wall of easing half'2l and a plate 35 secured between the side walls thereof. The left end of plate 3| ends in a turned up portion forming a bridge 36, which may also be seen in Figs. 1 to 4, said bridge acting to limit the.

there under the hinge block 28 and bridge 36 into 5' corresponding channels in casing half 20, formed by fins 44, 45, 46 and 41. These type-bearing strips preferably are of a combined cloth and porousrubber construction, the backing which is seen in Fig. 5 being of cloth and the type, such as type 48 in Fig. 4 being of porous resilient rubber. The porous rubber type are intended to be impregnated with ink and the particular mechanism by which plate 3| is moved by button 33 is to facilitate the reinking of such porous rubber by providing for the protrusion of the selected type against a felt pad flooded with ink, as will be described later in connection with Figs. 7 'and'9.

Referring to Figs. and 6, the bottom of plate 3! is grooved as at 49, at intervals therealong corresponding to type positions, such grooves acting as locating detents for stud-like locating pins, such as pin 5| attached to a finger-moved locating button 52 secured to the end of a typical type strip 53 that is accom modated inf'ca si'r-igihalf .2 f. The locating buttons for type strips 4|, Hand 43 are shown in Fig. 5 at 54, 55 and 56, respectively. Referring to Fig. 3, the detent grooves in plate 3| are formed,

by boring holes, such as holes 51, through the fins of plate 3|, so that they will groove the bottom of plate 3|.

Referring to Fig. 5, the left-end: ofeachtype strip is secured to a spring anchored in the end of casing 20, as for example,- spring -58, which-- and 6ttforatype rstripslz and 43 hold the free endssofithe,type'strips" so that in folding the hand-Istamp to a closed position the selected typeemay-be-iaccuratelyfmaintained at theprintin'gixpoint; The bottomi formation of the locating buttonsias seen Fig;,6permits them to be pushed slightly to release-the detent pins. As seen in-zFigi-z5, the selected type is positioned, in the opened condition ofthe casings, at a point just-itoitheleft'of the bridge 36; As the hand stamp is folded .to the closed position the bridge comes=to the positionshown in Fig. 3 with the selectedtypesupported thereby,- ready for printing.

Itzwill be-qapparent' that, the'height of thetypezwith'referenceto'the ears 24,- 25, 26 and- 21, as seen in Fig: 1, will permit only a slight sdi-leezerimpression. of the-.type against record material F19:-

Itisidesirable in re-inking porous type that asrmuch of-:the type'bodyas-possible come in contactwith an inking; pad.- To facilitate such re-inking, means is provided to move the selected type outwardly of the closed case by,

movement ofbridge 36 away from hinge block 23-1upon-inward movement of button 3!.

Theprinting-strip ll-isshown positioned so that-a-blank space is-at printingposition, that is,-;to;sayno type character is to be printed inethat column. The provision of the stopli m-i-ts afforded by-formations 24 to 21, inclusive, prevent tiltingof the stamp unit as it is applied to record material, and thus prevents smudging of the print.

Although-the hand stampv was primarily designed for use-withv porous resilient-type, it may be; also usedwith the conventional rubber type, that is to say, solidrubber type, by usingit in conjunction with an'inking pad, orequivalent.

To fully; i1lustrate-the utility of the type project-ingmechanism for re-inking, reference is maderto Figs-b'l and 8, which showthe hand stamp resting in the socket!!! of. there-inherqanh In ZFig; -7 the stamp. is shown in normal The springt=58-forstype strip 4i and the springs 60 4 position with the edges of the casing ends near the hinges resting on projection 1!, wherein the type are out of contact with an inking felt 12, it not being desirable to leave the porous rubber type in continuous contact with the felt pad 12. The neck 10 acts as a convenient supporting place for the hand stamp when not in use and=the-snug+fitting collar "HT-actsas a seal against atmospheric drying of the ink In Fig. 9 the inking process is shown wherein by pushing inwardly on button 33 the type are caused to.come in contact with the ink-impregnated felt'lZ. The can 13 is provided with flexible sides whichmayrbe-pressed inwardly to force .ink -:14 through a delivery pipe 15 to flood the felt 72;-

In operation, the hand stamp is opened, the selected type moved to the printing station throughthe movement of locating buttons 54, 55 and 56, which are pressed in with the finger and-then-movedtothe proper detent position, the casing isuclosed and the unit is used as an ordinary handistampr Thechief novelty. of the invention resides in the spring tension imposed 'upon the type strips, the. impression-limiting action of the hinge ears, the projecting. means by which type is protruded to where it may be readily inked and the detent means fonaccurately positioning the eet m While the form oflmechanism herein shown and described is. admirably adapted to fulfill the objects-primarily, stated, it is to be'understood that it is'- not intended to. confine the invention to th'e one form or em'bodiment herein disclosed, for'it .is susceptible of embodiment in various. other forms.

What is claimedis:

1. A printingstamp, including, in combination, twomatingcasingi pieces each open at'one end and hinged. togetherso as to be adjustable to open condition with the open ends facing each other to form a, continuous hollow space from one casingpieceto the other, and foldable to closed condition with the casing pieces in side-to-side contactand the. open endsfaced in the same direction;- one or-more flexible strip-like printing elements housed inthe hollow spaces ofsaid casing pieces and-of shorterlength than the combined lengtheoflsaidhollowspaces so as to be selectively movable back and forth between the' ing-the..other.-,-end. of each of saidstrips to the.

end of the other..casing.piece,opposite the hinge, whereby saidstrips in their adjusted position are tautly. but resiliently held.v

2. The deviceof claim 1, in which hinge ends,

of -said casingpieces are so formed as to act as limit stopslto' prevent excessive squeezing of the selectedtype'on a printing operation;

3. The printing stamp ofclaim .1, in which a bridge piece is provided at the hinge whereby the type .positioned at"said hinge are supported by saidlbridgepiece; saidibridge piece being movably mounted so that it may be moved to a position where the type selected are protruding beyond their normal printing position.

4. A printing stamp like that of claim 1 having formations thereon which act as limit stops in making an impression with said type on record material; and means movable to protrude the selected type from the container for re-inking.
